"Architecture for a node of the telecommunication service, and processes to introduce or modify the applications of telecommunications service stored in a node of a telecommunications service.And to operate a knot of telecommunications service providing services ".A node of a telecommunications service (10) includes an architecture of multi - level including a layer of operating system (12) inter facing using an interface linked at compile time (22).A layer of service structure (14).And an application layer service (16) inter facing unsando an interface connected in time of operation guided by objective (22) to the layer of service structure.Link in the operation time of service applications supports the introduction or modification of service applications during implementation in operating time (74) of the node of the service.Each application service inherits from the same base class (32), and is defined by certain criteria (18) that need to be met to execute the service.An operator (28) maintains a reference to each application of service available.When a certain service needs to be performed (40), a set of criteria for the right service is evaluated (44) by the operator.And a particular applications of service within the service layer defined to meet the set criteria is selected (46).The application of the selected service is then invoked (52) to support the right service.Following the termination (56) of the application of service invoked, the service is interrupted (60) in a controlled way.
